Title: Metering powders to pelletising machine - using rotating double arm fed from hopper running on smooth bed
Inventor: AKIRA HIRAI
IPC: B30B15/30
Filed: 1976-09-22
Abstract: Metering system has 2 virtually horizontal and hollow metering arms. These are mounted in a bearing on the base of a feed hopper and are rotated around a flat surface. Powder can be fed smoothly and uniformly from the hopper into the arms. The other end of the arms are sealed by the contact between them and the flat bed. This forms the metering outlet and it runs over the pick up former for the subsequent pelletising or tablet making operation. These are several hollow moulds which become precisely filled with powder and into which the stamping die then descends to form the tablets. System is esp. for use with powders of vegetable origin such as powdered garlic. Such powders are usually very light and difficult to form into satisfactory tablets.

Patent DE-2900960-A1 (DE)
Inventor: WEDER RINO
IPC: F17D5/04
Filed: 1979-01-11
Abstract: In order after the restoration of an underground tank installation also to be able to check the pipeline (27) between the tank (12) and oil burner (15) for leaks, a flexible, and yet relatively stiff plastic tube is inserted into this pipeline (27), it being possible for the cavity between the plastic tube and the pipeline (27) to be checked by a vacuum gauge unit (17) which also serves to monitor the tank (12). Various types of connection are possible for this purpose, consideration also being given to the special conditions in the case both of a single-walled and of a double-walled tank. Thanks to a circulation line (35), a special oil return pipe is superfluous, so that both the oil suction pipe and the oil return pipe can continue to be used in the installation, whether it be as a part of a double-walled line (26) or, e.g., as a measuring line (21). <IMAGE>
